I just got my first shipment of Jet Central engines and I see it comes with Troy Built 5400 Mah Li-Ions! I was shocked. So shocked I thought it was a mistake. I called Eric at Jet Artes and inquired about it, and he said all the engines except the Super Bee come with the Li-Ion packs. The Super Bee comes with the standard "smoke pump" battery.

Anyway, this was news to me so I just though I would share it for anyone trying to decide which engine to go with.

Oh, don't fotget that little detail about the lifetime warranty.
